TANK-CAB.

residing .at Berwick, Columbia county,

Pennsylvania, and being a citizen of the United States, have invented certain new and useful Improvements in -Tank-Cars,.of which the following is afull, clear, and

exact description, such. as willenable others skilled in the art to which it appertains to make and to 'usethe same, reference being had to the accompanying drawings, which illustrate the preferred form of the invention, though it is to be understood that the invention is not limited-to the exact details of construction shown and described, as it is obvious that various modifications thereof will occur to persons skilled in the art;

In said drawings: Figure L is a side ele-.

vational view partly in section illustrating the invention applied to a tank car. Fig. 2

is an enlarged fragmentary view partly in I section, the section being taken on line 22 of Fig. 4. Fig. 3 is a transverse sectional View, section being taken on line 3- 3 of Fig. 2. Fig. 4 is at the right a plan view of the details shown in Fig. 2, and at the left a transverse section, the section being taken on line 44 ofFig. 2. Fig. 5illustrates in longitudinal section a modification of the so after described, and Fig. 6 is a central verdevice shown in the other figures, as hereintical longitudinal sectional view showing a slightly modified form of wedge suspension.

It is well known that tank cars used for transporting fluid products comprise, generally an underframe with tank suitably mounted thereon and held in position between-end head blocks or by central anchorage of some suitable type preferably includa center anchor casting or anchor-desuitable lugs or abutments therefor secured the underframe of the car to prevent longitudinal shifting ofithe tank on the underframe', and the tank being-held in position on the underframe; by conventional tank Owing tothel natureigfthe lading it is position; in snclpmanner-as to, prevent some slight londi'tudihal shifting, which shifting'j is consider'edadisadvantage.

v To overcome difiiculties heretofore encountered the" present 1nvent1on comprises ananchoring means adapted to anchor the I tank of a tank car to its underframe in such manner as to prevent longitudinal shifting of the tank, and at the same timeto so connect the tank to the underframe as to prevent separation in a vertical direction under normal conditions, but with the parts so disposed and so operative that when it is desired toseparate the tank from the underframe this may be readily accomplished without destructive effort.

The invention applies particularly to the anchorage shown and described in Reissue Patent 12832, of July 21, 1908, issued on the application of John McE. Anies, and is in the main. supplemental thereto, though in the modificationshown in Fig. 5 the device departs from the principle of said Ames structure, as hereinafter more fully set forth.

Referring to the parts: 1 is a car body or tank of the conventional for provided with longitudinally extending bottom sheet 2 and mounted above the underframe, comprising center sills 3-3 with bolster 4, and short side sills 5, or not, as may be desired, no part of the underframe, except the center sills, being essential to the application of the present invention. By preference the anchor is centrally disposed. relativeto the length of the tank, but it may be positioned forwardly of the bolster 4: and between such bolster and the ends of the center sills; that is, between the bolsters and the couplers.

In the embodiment of the invention diselusive, lugs or stops 6 are attached to the center sills 3, as shown in'Fig. 4:. These lugs span the space between the center sills, and are riveted thereto and form connec tions for the spaced'center sills, which will effectually prevent buckling of the center sills during buifing. Depending from the tank in the figures referred to is a center anchor casting 7, which, as shown in Fig. 3, 1S provlded with an arcuate top flange 8,

conforming to the curvature of the bottom sheet 2 of the tank and is riveted securely thereto. The center anchor casting comprises spaced walls extending longitudinally iietweenthe sills 3, and between these walls the outlet valve IOfroni the tank passes, as

is usual in anchors of this type, there being a clear space between the walls or spaced depending flanges 7 of the anchor casting for the passage of said outlet valve.

Connecting the walls 7 at each end I provide a transverse wall or end flange 12 which serves as a connector for the walls 7, adapted to cooperate with the stop which is interposed. between said walls 12 and the lugs 6, before referred to. The center an-' chor casting thus far described forms no mental to the descri" the present inven ,n

part of the present invention but supplearts of said casting particularly applies and includes an eiiitension of said casting,

as shown in the drawing.

' At each end of the centeranchor casting 7, shown in Figs, 1 to a inclusive, the part thereof depending, below the flanges 8 is reeach end of the cessed at '13 providing anchor casting a plur'al'ftypf pockets which are adapted to receive therein the square heads 14 of long bolts15, which are held in said pockets 13 with the stems of said bolts depending, the bolts being screwthreaded for a convenient distance at their lower ends and having slipped thereon the block or wedge 16, which wedge is preferably provided with a straight vertical face 17 where it contacts with the outer face oi.

the end walls 12, before referred to, and is provided with an. inclined face 18 atits opposite side 5- that is, the side of the wedge next adjacent the lug 6, before referred to, so that when the wedge is moved upwardly it will contact with. an inclined face of the lug 6, thereby locking the tank firmly in position, 16 are placed, as shown in. Figs. 1 to 4, inclusive, with one wedge interposed between each wall 12 and the contiguous lug 6.

Adjusting nuts and lock nuts 20 and 21 are provided for well known purposes. By using'the wedges in connection with. the center anchor of the before referred to reissue patent, it is obvious that the tank may be more firmly locked in its position than could. be with the structure disclosed in said patent. It is well known that tanks of tank cars are heavy bodies which are ordinarily lifted by means of power cranes, and extreme care must be taken in placing the tank in position under normal conditions, in ad' ditionto which some clearance between the center anchor casting 7 and the stop lugs 6 is required to facilitate placement of the tank, which clearance, even though very small, sometimes permits independent movement of the tank on the underfralne. When the wedges-16 are used, as before described, it is evident that the tank may be placed in position with the bolts 15 merely resting in the pockets therefor and depending with the casting 7 between the stop lugs 6, after which the wedges '16 may be placed in poit being understood that the wedges sition and tightened so as to firmly lock the tank in a desired position.

-There is a positive advantage in using the wedge of this invention, in that the rigidity of: tank and under-frame are assured and there is no necessity for perforating'thece'nter sills for the passage of transverse keys which have been suggested as ameans for anchoring the tank on the underfram, The same feature of advantage may be secured by the use of the wedge shown in Fig. 5,

which. is adapted to cooperate with an anchor member 7 depending from one end: of

the tank, which anchor member is provided I with the wall l2 extending transversely ;be-

tween center sills, as 3, the wedge 16being interposed between said wall IQXandanex-l tension 6, which is castrintegraliwith and .1

forms a part of the'bolster'center fillerjcasting, which center filler casting is common in the art.

An advantage of the end anchor construetion disclosed in Fig. 5 over the center an-j chor construction shown in the other fi-g-.

- ures is that the tank is more firmly held in position at the bolsters, so that rocking of the tank on its underframe is positively re-,; vented. In the constructionvshown in igsL 1 to 4, inclusive, the central tank bands BB could be omitted, because thetank and underframe are held-against vertical separation by means of the interlocking of;

bands C may be omitted'because the tank the bolsters, audit is to be noted.in connection with both details of anchor that the longitudinally extending portions of the anchor walls rest in close proximity to the inner faces of the center sills and substantially, though not entirely, fill the space bethe wedge 16 with the lugs 6, while-with the p construction shown inFig. 5 the end tankv is in that construction rigidly secured to tween said center sills, said walls extending downwardly to a considerable distance below the tops ofsa d center SlllS, so as to pro vide means to prevent tipping or rocking of .the tank on its underframc. Thewcdges j likewise also extend substantially from center sill to center sill, there being only such p v clearancebetwecn the wedge and the sills as 11s necessary for convenlent manipulatlon of the parts. Thus it will appear that the anchor forming the subject-matter of the greases of'placing thewedge its operative position.

When desired t e wedge and its holding bolt me be carried by the stops rather than by the spending casting on the tank itself,

and thestop 6 in Fig. d'has a transversely extending projecting overhang or head 19, vsupported by which head and depending therethrough are the bolts 15- supporting the casting 16, as hereinbevfore described.

It is obvious that while two wedges have been shown with each car it is within the skill of a mechanic in view of this disclosure to incline one of the transverse walls 12 so as to fit the downward and rearward inclination of the abutting face 18 of the stop 6 and make use of one of the wedges 16 at the opposite end of the casting or car body, it being understood that the tank or car body is lowered into position between the stops, and the driving of one of the wedges will force the inclined face at the opposite end into engagement with the inclined face of the stop. 7
